Question 90mm t-body ?
Do you have to retune for a 90mm t-body or are they the same ?

he's all out of whack here lately.

You don't need to retune if you are worried, but a tune could be massaged for sure.

your engine came with a 87mm TB, just want to make sure you know that before you buy one a few mm larger.

Yes I know what was stock but I just installed a MP112 Blower and I used the 90mm T-body since the J-tube was 90mm as well.
But was wondering if I needed to tune for the bigger t-body ?

It will run fine without a re-tune. There are some adjustments to ETC area scaler that may help it idle a little better. I've not touched mine and 90mm for couple years now.

Ur going from 87mm to 90mm? U can prob tweak it a little but I cant believe its gonna be too material if u dont change the tune. I had mine ported and tuned...its all incremental IMO...searching for pieces of ponies when there still might be whole lots left to find by solving IAT's and bumpin up boost.
